Waialua is young, but it¡Çs already legendary. First planted in Oahu in 1995, it originally came from the Big Island. Though it has a similar flavor profile as Kona, its semi-sweet flavor are unique to the central highlands in the Waialua region. Don¡Çt sleep on these beans: The 200-acre farm that grows this coffee only produces about 160,000 pounds of unroasted beans annually, so it always sells out.
